/* ==========================================================================
   StratiLogger — the unauthenticated pages (sign in, sign up, reset, …).

   THIS IS THE SEDSTRAT LAB THEME, NOT THE APP THEME.
   The sign-in page is the one screen a visitor reaches straight from
   sedstrat-lab.com, so it is dressed like the landing page rather than like
   the workspace: flat colour, one 2 px charcoal outline, soft-rounded corners,
   Poppins for headings and Inter for body. Everything past the sign-in button
   is the app's own Flexy theme (shared/theme/tokens.css); this sheet stops at
   the door.

   The palette is the one sampled off brand/sedstrat_logo.png in the
   sedstrat-lab-site repository — keep the two in step by hand:
     charcoal #1B2123 · green #6EB357 · yellow #FEDC4B · cyan #42C2D9

   The fonts are the same two the landing page loads from Google Fonts, but
   SELF-HOSTED (static/web/fonts, latin subset only, ~60 kB). The field wifi
   this product is built for is exactly where a third-party font request hangs
   the first paint, and a sign-in box should never wait on fonts.gstatic.com.
